AXLE-SPINDLE AND VEHICLE-=HUB BOX.

SPECIFICATION forming part of Letters Patent No. 648,177, dated April 24, 1900.

Application filed December 26,1899. $erial No. 741,629. (No model.)

To alt whom it may concern:

Be it known that we, FRANK PALECK and BOHNMIL WALTER, citizens of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented a new and useful Means for Adjustably Mounting Axle-Spindles in Vehicle -Wheel Hubs, of which the following is-a specification.

Our invention relates to mounting axlespindles within the hubs of vehicle-wheels; and our object is to provide a construction whereby the end shake of the hub-box upon the axle-spindle may be easilyand quickly adjusted, and being adapted to greatly increase the bearing-surface the wear upon the collars is greatly reduced when compared with many kinds of axle-spindle bearings of the ordinary construction, the same being fully described hereinafter, and illustrated in the accompanying drawings, in which- Figure 1 is an axial section of a vehiclehub with the box and adj usting parts on an axle-spindle, which latter is shown, together with a portion of the axle, in side elevation.

Fig. 2 is an axial sectionof the hub-box to show a shoulder-ledge near the center of lengthinside. Fig. 3 is a side elevation of the axlespindle and a portion of the axle with right and left screw-threads, indicated at the outer end of the spindle, and showing a short groove to receive an inward projection in a lock- Washer, which is shown in side elevation in Fig. 4, with a central hole adapted to receive the outer end of the axle spindl'e and the pro jection to engage in the groove therein. Fig. 5 is an outer end elevation of the axle. Fig.

6 shows, respectively, an axial section and an outer end elevation of a long combined collar 1 and nut for adjusting the amount of end shake-of the axle-box on the axle.

Similar letters indicate like parts throughout the several views. I

A is a vehicle-hub of any desired construction, and Within the hub is a box B, having a shoulder-ledge Within it, near the center of length in this instance, as indicated at C.

stance being right and the threads at G being i left hand. Screwed upon the larger threaded portion Fof the outer end of the axle-spindle is the long collar and nut H, whose inner end portion is not usually threaded, but projects inwardly along the outward end portion of the spindle far enough to contact the outer shoulder I of the box-ledge C, while the outer shoulder E of the axle-spindle contacts the opposite shoulder J of box-ledge C.

At K is a washer adapted to slide onto the small outer threaded portion of the axle-spindle,and the inwardly-projecting part'Lthereof engages within the groove M of the axle, and is thus free to slide in and out upon the spindle end, but cannot revolve.

' to the desired position and then securing same in position by screwing up the outernut, so that washer K is clam ped closely between the two parts H and N.

We olaim asour invention' In a means for adjustably mounting axlespindles withinvehiole-wh'eel hubs,'a box disposed axially through the hub, and having the usual shoulder-bearings at each end, in

combination with an inwardly projecting ledge forming shoulders facing'toward opposite ends of the box, an axle-spindle mounted through the box, and partly in contact with the surface thereof, a collar at the axle end ofthe' spindlein contact with the shoulderof the box, and a shoulder on the axle-spindle within thebox incontactwith the inner shoulder of the ledge, a collar adj ustably secured around the outer end portion of the spindle and with the inner end portion thereof in contact with the outer shoulder of the ledge, the,

inside peripheral'surface of the'box, and the outer end bearing-shoulder thereof, for-the purpose hereinbefore stated.
